DESCRIPTION

Technical field

The present invention refers to a lighting system, in particular adapted to provide localized lighting according to the needs of use, to avoid waste of electricity and improve the performance of the lighting system.

The present invention also refers to a conversion kit, applicable to a lighting system to vary its operating characteristics according to the needs of use.

In general, the present invention finds application in the field of lighting civil or industrial environments, such as large and spacious environments that people access by occupying limited areas.

Known art

There are situations, in the civil or industrial field, in which large rooms need to be illuminated, so that people can access and work in them safely. The lighting of an environment obviously involves costs for the electricity spent. Wanting to consider energy saving and efficiency improvement issues, it is advisable to use low energy consumption light sources, and turn them off when not needed.

An exemplary category of industrial environments in which adequate lighting is important is represented by the textile sector, that is weaving and spinning.

In the textile sector, industrial environments have a high presence of machinery that can operate in semi-automatic mode; the presence of the operator is required only for start-up and shutdown operations, or in case of machine malfunction (for example, for the breaking of the warp thread on a loom). Nevertheless, the presence of adequate light sources (also as required by the UNI EN 12464-1 standard) is necessary to allow the operator to perform his duties correctly and to verify that the chromatic qualities of the fabric comply with the requirements.

In particular, the spinning and weaving mills are often without windows in the areas where the operations with visible fabric are carried out, to prevent direct sunlight from damaging the fabrics. In such situations, the lighting is entrusted to the artificial light produced by lamps, mostly fluorescent, which can remain lit throughout the processing period which, as a rule, extends 24 hours a day.

Solutions are therefore known to make the use of lighting equipment more efficient, which can be categorized according to two strands.

A first trend involves optimizing the lighting source used in the lighting bodies, for example by using energy-saving LED or similar technologies.

A second trend involves dynamically controlling the lighting of the environment, reducing the light intensity or even turning off the light sources in areas where, at a given moment, there is no need for lighting.

In this second line, there are lighting equipment solutions that vary their operation based on presence sensors, which typically use the following technologies: motion detection, for example by means of the classic "photocells", and heat detection, by means of thermal cameras that identify hot bodies similar to operators.

However, the aforementioned solutions cannot be effectively used in workplaces with automatic or semi-automatic machinery, because the latter involve movement and heat generation, which would activate the sensors even when, in principle, lighting would not be required.

Still in the second line, a further solution is described by the document US86S6647B2 which refers to a lighting system with a plurality of light sources, in which a sensor equipment detects the presence of a person in a particular position, and a control system it foresees to vary the luminous intensity of the light sources, increasing it in correspondence with the detected position and reducing it elsewhere. Document US8686647B2 proposes to use image recognition sensors for detecting the presence of a person, by means of suitable recognition algorithms, and to assign a position in the monitored space.

The image recognition sensors proposed by the US8686647B2 document are however not optimal, because they involve a high cost (each sensor is, to all intents and purposes, a video camera and a significant computing power is required for image processing) and they work in a unsatisfactory in the case of obstacles or machinery of high height, which could "hide" a person from certain points of view.

Still in the second line, another solution is described in document EP2906880A1 which refers to a system for determining the occupation of commercial spaces, through the synergistic use of multiple types of sensors.

Document EP2906880A1 proposes to use combinations of multiple sensors, to exploit, among other things, mobile / cellular terminals that connect to Wi-Fi networks, also to triangulate their position.

The system proposed by EP2906880A1 consists of a monitoring system for the entire commercial building, and categorizes the sensors based on the "spatial resolution" they can provide on the presence of people or groups of people. This system allows the control of the building services, such as lighting systems and air conditioning or ventilation systems. The monitoring system of the entire building proposed by EP2906880A1 is precisely optimized for environments such as shopping centers.

However, the system proposed by EP2906880A1 is not applicable flexibly to industrial or domestic environments, in particular due to the complexity of accurately locating the presence of operators, sometimes single, in large environments where there are moving machinery, and in which it is not necessary, for example, to illuminate an entire room such as a warehouse. In this regard, it should be noted that EP2906880A1 does not recommend the use of dedicated sensors (such as C02 sensors, acoustic / sonar sensors, video cameras, or short-range radiofrequency sensors) as they would entail excessive costs for monitoring the environment.

Unfortunately, in the known art there are no solutions that fully satisfy the needs of energy saving, effectiveness, flexibility and economy.

Summary of the invention

An object of the present invention is to obviate the drawbacks of the known art.

A particular object of the present invention is to ensure correct brightness in an environment, by adjusting the light sources.

A further particular object of the present invention is to provide high luminous intensity in the vicinity of "operating areas", only when necessary.

A further particular object of the present invention is to reduce the luminous intensity in "non-operating areas".

A further particular purpose of the present invention is to reduce electricity consumption for lighting, thanks to the control of light intensity.

A further particular object of the present invention is to more effectively detect the presence of people in an environment.

In this way, it is possible to vary the lighting parameter of the lighting devices so as to ensure the correct brightness of the environment, based on the position of the occupant or occupants. In particular, it is advantageously envisaged to provide a high light intensity only in the vicinity of "operational areas", when necessary, while it is possible to advantageously reduce the light intensity in "non-operational areas", thus reducing electricity consumption for lighting.

In addition, the detection of the position of the occupants in the environment becomes more effective, even when the latter was occupied by machinery in operation or various sources of disturbance, thermal, acoustic or visual, which could make the location less reliable. The present invention makes it possible to detect the position of the occupant or occupants even in the presence of heat sources or continuously moving machinery, and is therefore particularly suitable for use in industrial environments.

Then, the present invention allows to guarantee the visual comfort, safety and well-being of the workers or occupants of the environment, providing lighting adjusted according to the specific needs and the contingent situation, even improving the lighting available in the position of the occupants. .

Furthermore, advantageously, the lighting system allows you to locally adjust the lighting according to the needs of use, based on the detected position of an operator, the activity carried out, and also the regulatory requirements, the energy saving desires, safety. and natural lighting.

A particular advantage of the present invention is the creation of localized areas, in the environment, with different light intensity based on the position of occupation by operators.

The present invention allows to optimize, among other things, the costs of construction and installation of the system, the precision of the localization of the mobile markers, the integration with the communication and control system of the lighting parameter, the flexible communication between the elements. of the system.

The present invention provides embodiments, in which a lighting system can be co-located within each lighting device, to directly and locally regulate the luminous parameter; or it can be centralized by means of suitable more or less remote control means capable of individually controlling a plurality of lighting devices.

A further aspect of the invention provides a kit of parts for the conversion of a lighting system, comprising: localization means configured to detect the position of at least one occupant in an environment, which comprise: at least one mobile marker suitable for transmitting a signal in radiofrequency and at least one detection device for the mobile marker adapted to be installed in the environment to receive the radiofrequency signal; the localization means are adapted to detect the position of the occupant starting from the radiofrequency signal emitted by the mobile marker. The kit of parts further comprises control means configured to adjust an illumination parameter for each individually of a plurality of illumination devices. The control means are further configured to vary the lighting parameter for one or more of the lighting devices, based on the position detected by the locating means.

In this way, it is possible to convert a traditional lighting system, having traditional lighting devices, into a lighting system according to the present invention. Advantageously, this conversion allows you to reuse pre-existing components of the lighting system in a functional way, adding the parts that allow you to implement a lighting system designed to provide localized lighting according to the location of the occupants in the environment, as illustrated above.

The lighting system 101 according to the present invention then comprises the localization means 105 configured to detect the position of at least one occupant in the room 10.

In fact, in the room 10 there may be one or more occupants 11, such as workers or visitors. According to the present invention, the "occupant" is typically a person, but it could also be a vehicle or mobile machinery, such as a forklift or forklift, or such as a "transpallet" or even a simple trolley moved by operators. In general, an "occupant" is a person or object that occupies a limited and restricted portion of the environment 10, being able to move within the latter and requiring localized lighting.

Furthermore, in the environment 10 there are for example machinery 12 or equipment, which can be in continuous movement, which can represent even intense thermal sources and which are typically voluminous and bulky, being able to represent obstacles to the line of sight inside the environment 10.

The control means 103 are configured to vary the lighting parameter for one or more of the lighting devices 102, based on the position detected by the locating means 105.

Focusing on the locating means 105, they comprise at least one mobile marker 107 and at least one detection device 108 for the mobile marker 107.

The mobile marker 107 is able to be associated with the occupant 11 and to transmit a radiofrequency signal 109 in the environment 10.

In this sense, the mobile marker 107 can be an identification plate, "tag" or other element easily worn by the occupant 11, for example inserted in a badge holder or in a safety helmet, or hung around the neck. The occupant 11 carrying the mobile marker 107 becomes the focal point for the lighting system 101, which varies the lighting in the room 10 according to the position of the occupant 11.

The detection device 108 is adapted to be installed in the environment 10 to receive the radio frequency signal 109 emitted by the mobile marker 107. Preferably, the radio frequency signal 109 is transceived and exchanged between the mobile marker 107 (at least transmitting) and the device 108 (at least receiving) according to one of the following protocols: Ultra Wide Band or Wi-Fi or RFID or radio waves or Bluetooth.

The localization means 105 are adapted to detect the position of the mobile marker 107 within the environment 10, starting from the radio frequency signal 109. For their part, the control means 103 are configured to activate one or more of the detection devices lighting 102a, 102b, 102c or 102d which are installed at the detected position, so as to provide adequate lighting only where required by the location of the operator 11.

In particular, the control means 103 comprise at least one control unit which is adapted to control the plurality of lighting devices 102.

Therefore, the electrical power supply of the lamps 104 and one or more signals for the individual variation of the lighting parameter of each lighting device 102a, 102b, 102c or 102d.

In the example considered, reference was made to the lighting devices 102 as comprising a single lamp body. The present invention is applicable to lighting devices which each comprise one or more lighting bodies and / or one or more lighting sources,

In one embodiment, each lighting device could comprise a group of lighting bodies, also separate from each other; for example, the control means could command the switching on of an entire "row" of lamps, which constitutes a single "lighting device" according to the terminology adopted here.

In yet another embodiment, the lighting system could comprise one or more light intensity sensors, arranged in the environment 10 and configured to detect a quantity of natural lighting present in the environment, for example coming from windows or other openings that allow access of natural light. It is envisaged to communicate the quantity of natural lighting thus detected to the control means 103, in order to further vary the lighting parameter. For example, if an occupant were near a window during the day, it may not be necessary to activate the lighting device at the window.

Figure 2 illustrates the operation of a lighting system 10 Γ corresponding to the embodiment described with reference to Figure 1.

In this example, in room 10 there are four detection devices 108a, 108b, 108c and 108d, which can triangulate in the room the position of the movable markers 107a, 107b and 107c associated with as many occupants.

The control means 103 are configured to vary the lighting parameter for one or more of the lighting devices 102, based on the position detected by the locating means comprising the detection devices 108.

In particular, the control means 103 are configured to selectively activate the lighting devices 102 which are installed at the detected position of the movable markers 107a, 107b and 107c.

In general, the control means 103 receive as input position information obtained from the locating means, and determine the areas affected by the lighting devices in which to adjust the lighting parameter, among other things ensuring: the correct amount of light where required , the minimum lighting for energy saving where possible, in compliance with any regulatory constraints in order to ensure safety, visual comfort and well-being for the occupants of the environment 10.

By "activate" we mean, among other things, to cause an ignition or to increase the light intensity of the light sources. The activation of the lighting devices 102 is represented in Figure 2 by means of a percentage of light intensity indicated for each control device. lighting, whereby 20% of luminous intensity is reserved for areas of the environment 10 not occupied by mobile markers 107, while 100% of luminous intensity is provided in correspondence with the detected position of the movable markers. The intermediate zones are affected by suitable brightness gradients, from 30% to 90% etc., meaning that these values are purely examples and can be adapted according to the characteristics of the environment 10, of the activity carried out there, and of the lighting devices 102.

In general, the lighting system is also designed taking into account the position of the operating areas which require adequate lighting, the level of natural lighting, the persistence of abnormal or dangerous situations.

In a preferred embodiment, there are alarm and danger apparatuses operatively connected to the control means 103, to adapt the lighting according to appropriate strategies. In case of anomalies or alarms, the control means are configured to vary the lighting parameter according to predefined criteria. In one example, it is planned to adjust the lighting parameter to create a clear and defined light path to leave room 10 even in the presence of smoke. In another example, it is planned to adjust the lighting parameter to adjust the lighting devices to maximum light intensity, to ensure the carrying out of emergency operations.

In general, if a fault occurs in the lighting device, it is provided that the control means, or the lighting devices autonomously, regulate the luminous parameter to the maximum luminous intensity.

Figure 3 illustrates a lighting system 201 according to the present invention.

The control means 203a and 203b are adapted to control the respective of the lighting devices 202, to individually adjust the lighting parameter thereof.

The lighting system 201 further comprises locating means 205 which detect the position of the occupant 11 in the room 10, so that the control means 203a and 203b can vary the lighting parameter of the respective lighting device 202a and 202b, according to the position detected.

The localization means 205 comprise at least one mobile marker 107, already described, and the detection devices 208a and 208b for the mobile marker 107.

The detection devices 208a and 208b are each associated with each of the lighting devices 202a and 202b, respectively, and are adapted to detect the proximity of the mobile marker 107 in the environment 10.

In this way, each lighting device 202 detects the proximity of the mobile marker 107, and the control means 203 installed inside it regulate the luminous parameter in order to provide adequate lighting to the operator 1 1.

The detection devices 208a and 208b are then installed in the environment 10 to receive the radio frequency signal 109 and detect the position of the mobile marker 107 starting from the radio frequency signal 109.

To detect the proximity of the mobile marker it is possible, although not only, to use methods that exploit the wave attenuation of the radio frequency signal 109.

In general, any number of detection devices is provided, provided that each is associated with a respective lighting device and respective control means, for the variation of the lighting parameter.

In this embodiment, the communication system which connects the control means 203, the detection devices 208 and the lighting devices 202, preferably comprises a short cable connection. In a variant, the detection device could be completely integrated in the lighting device, for example in the lamp driver, preferably together with the control means as well.

Also in this embodiment, a light intensity sensor can be provided to detect a quantity of natural lighting in the environment 10 and to further vary the lighting parameter, as already described.

Figure 4 illustrates the operation of a lighting system 201 'corresponding to the embodiment described with reference to Figure 3.

In this example, the lighting devices 202 co-locatedly comprise the control means 203 and the detection devices 208, to activate one or more of the lighting devices 202 which are installed at the detected position of the movable marker 107.

In particular, the control means 203 are configured to selectively activate the lighting device 202 to which they are associated, if they detect proximity to the detected position of the movable markers 107a, 107b, 107c and 107d.

In this way, each individual lighting device is configured to detect a mobile marker in its proximity, to vary the luminous parameter, for example by adjusting the light intensity to be provided.

It is therefore possible to ensure optimal regulation of the lighting parameter, among other things by guaranteeing: the correct amount of light where required, the minimum illuminance for energy savings where possible, in compliance with any regulatory constraints in order to guarantee safety, visual comfort and well-being for the occupants of the environment 10.

Also in this embodiment there may be logics for managing alarms or anomalies, according to what has already been described.
